Pollen-connecting threads inHeliconia (Heliconiaceae)
Plant Systematics and Evolution, 1995InHeliconia thread-like structures connecting the pollen grains are described. These threads are decay products of the walls separating the pollen chambers, and products of the rupture of the mature anthers in the stomium region. The pliable cell threads mix with the pollen and entangle individual grains to form aggregates. This ensures that the pollen

ULTRASTRUCTURE OF EXINE‐LESS POLLEN: HELICONIA (HELICONIACEAE)
American Journal of Botany, 1978Pollen of Heliconia and many of its relatives in the Zingiberales is virtually devoid of a conspicuous, protective exine. The exine is relegated to a few spinules and a thin, electron‐dense layer (0.08 μm), whereas the intine can be up to 100 times as thick (8 μm) and structurally complex.

Morphology and Phylogenetic Significance of Exine-less Pollen of Heliconia (Heliconiaceae)
Systematic Botany, 1983Pollen morphology of 27 species of Heliconia (19 species with pendent inflorescences; eight species with erect inflorescences) was examined using brightfield and scanning electron microscopy. Pollen of species with erect inflorescences has many character states in common with pollen of pendent species. Among the species with pendent inflorescences four
